DTCP2119THROTTLE ACTUATOR CONTROL THROTTLE BODY RANGE/PERFORMANCE
CIRCUIT DESCRIPTION
The Electric Throttle Control System (ETCS) is composed of the throttle m\
otor that operates the throttle
valve, the throttle position sensor that detects the opening angle of the throttle valve, the accelerator pedal
position sensor that detects the accelerator pedal position, the ECM that contro\
ls the ETCS, and the one
valve type throttle body.
The ECM controls the throttle motor to provide the proper throttle valve\
opening angle in response to the
driving condition.
The throttle position sensor which is mounted on the throttle body detects \
the opening angle of the throttle
valve, and it provides feedback to the ECM to control the throttle motor.
If the ETCS has a malfunction, the ECM shuts down the power for the throttle motor, and the throttle valve
is closed by the return spring. And the throttle valve is locked at a ce\
rtain opening angle. Also, the whole
electronically controlled throttle operation is cancelled until the system returns to normal and the ignition
switch is turned OFF.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P2119)
(a)Read the DTC using hand±held tester.
Result:
Display (DTC output)Proceed to
Only P2119 is outputA
P2119 and other DTCs are outputB
HINT:
If any other codes besides P2119 are output, perform the troubleshooting for those DTCs first.

CIRCUIT DESCRIPTION
The throttle motor is operated by the ECM and it opens and closes the throttle valve.
The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the
throttle body. It provides feedback to the ECM to control the throttle motor in order to regulate the throttle
valve opening angle properly in response to the driving condition.
If this malfunction is detected, the ECM shuts down the power for the throttle motor, and the throttle valve
is closed by the return spring. And the throttle valve is locked at a certain opening angle. Also, the whole
